STRAP-LOCKING DEVICE.

Specification of Letters Patent.

Patented Dec. 5, I916.

Application filed July 22, 1916. Serial No. 110,768.

To all whom it may concern:

Be it known that we, OBERLIN SMITH and Mrnns Gr. NIXON, citizens of the United States, said SMITH residing at Bridgeton, in the county of Cumberland and State of New Jersey, and said NIXON residing at Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Strap-Locking Devices, of which the following is a specification.

The object of our invention is to provide means by which a trunk-strap may be locked to a trunk by means of the trunk-lock and so prevent its being dropped off or stolen.

The following description and drawings make our invention clear.

In the various figures the same letter is used to designate the same part.

In Figures 1, 2 and 3, which are drawn to a smaller scale than the other figures, are depicted the front elevation of that familiar type of trunk-lock in which the lock proper is contained in the upper part of a hinged hasp. Our device, however, when designed especially for it, is entirely applicable to the older type of trunk-lock where the lock proper is attached to the trunk and its hasp attached tothe lid or, cover.

Fig. 1 is a side elevation of a trunk lock, of well known construction, with which our invention is employed; Fig. 2 is a similar view thereof, but with the strap applied; Fig. 3 is a like view illustrating a difi'erent embodiment of our invention; Fig. l is a front view of the device shown in Fig. 2, but without the lock or strap, and in an open position; Figs. 5 and 6 are bottom views thereof showing, respectively, the device before 'it is closed on the hasp and after it has been closed thereon; Fig. 7 is a bottom view of another embodiment of our invention; Fig. 8 is a side view of the form shown in Figs. 5, 6 and 7; Figs. 9 to 12 are detail views of the device shown in Fig. 3; Fig. 9 being a front view thereof; Fig. 10 a view partially in horizontal section and partially in top plan; Fig. 11 a side view; Fig. 12 a view from the back but with the device arranged at an incline so that it appears in a kind of perspective.

To illustrate our invention we show it applied to, or associated with the familiar type of trunk lock in which the lock proper is contained in the upper part of a hinged hasp, hat, of course, we do not limit our selves to that particular type of trunk lock. Referring now to the drawings for a clescription somewhat in detail, the letter A designates the hasp of said type of trunk lock and B the socket casing thereof, these parts being those, which, as is usual, are attached respectively to the body of the trunk and the lid of the trunk.

Referring particularly to the construction shown in Figs. 2, 4:, 5 andfi, our device is shown constructed of three parts, namely, the main member C, a flap E hinged thereto at one side and the pin F, which hinges the member C and the flap E, and in such construction the main member C and the flap E are preferably stampings of sheet metal. The main member C comprises what in effect are three parallel bars, the middle one G of which is depressed, or offset, inward from the plane of the portions of the bars above and below the same, and the strap D passes through the space lying between said two outer bars and said inner bar and in applying the device to the strap and hasp the portions of the main member C above and below the bar G are on the outer side of the strap and the hinge flap E lies between the inner side of the hasp A and the side of the trunk, and, hence, when the hasp is locked to the socket casing B, the flap E is inaccessible and can neither be gotten at nor moved to release the device from the strap; and as the main member C is provided, as clearly shown in Figs. 5 and 6, with an inturned end K that lies between the back of the hasp and the side of the trunk, it is impossible to swing the main member O upon the hinge F and effect the release of the device from the hasp.

In Fig. 2 H is shown a stop riveted to the strap. This member is sufiiciently long to prevent its passing through the oblong area provided for the strap, and so prevents the removal thereof. A similar stop may be provided below the device at I but may be dispensed with since the strapbuckle J will perform the function of the stop and prevent its withdrawal in this direction. With the strap in position as shown, to apply the device the hook-end K is passed under one edge of the hasp A, the flap being open as in Fig. 5. After the device has been settled into the position shown in Figs. 5 and 6, the flap is closed in as in Fig. e. The hasp is pushed heme and the sot ' Above the hasp A contained in the same ob- 7 long area is the strap'D. The strap is-rove strap and having stops to limit sliding movement ofthe strap and-prevent its sepa I strap being free 'to slip and slide as demanded by thebuckling, being, as clearl shown in Figs. 5 and 6, laced, or slid through the space provided in the main member C by offsetting the central portion G. In Fig. 7 a' second flap L, is substituted for the hook-end K, and performs the same function. Y

-The alternate form frontview, shown in V 'Fig. 9, top view in Fig. 10, side view in Figrll and a slightly inclined back view in Fig. 12, isa link of un-uniform section and consists of a single stamping or forgingof metal. It is so shaped that the hasp V A will fit into the lower part M of the device, holding it"down when locked.

through the device and the stop or stops riveted on. The device is then passed over the lock of the hasp as shown in Fig. 12, in which the strap is shown at D, the hasp at A, and the lock proper attached to the hasp,

at Ni The device is settled into position, the hasp is pushed home and locked which, as in the former case, prevents the removal of the strap; the latteris then buckled.

We'claimz Y I V '1. The combination of a trunk lock having a hasp, a trunk strap, and a strap engaging element extending over the hasp and ration from said element. V

2. A device of the class described having Copies of this patent may be obtained for and a strap engaging element adapted to lie over the outer side of the hasp and serving to slidably confine a strap over the hasp.

, 3. A device of the class described comprising a member that extends on all four sides of the lock hasp, a portion on one side of the hasp being pivoted, and having a strap guide through which the strap has a limited sliding movement.

4. A device of the class described comprising a member that extends on all four sides of the lock hasp, a portion on one side of the hasp being pivoted and having a strap guide through which the strap has a limited sliding movement, said guide being formed by ofisetting a portion of the member.

5. The combination with a lock having a hasp, a strap-securing device detachably connected with the hasp, and having on the outer side of the hasp an element that overlies the strap and allows sliding movement of the strap.

6. The combination with a lock having a hasp, a strap-attaching device comprising an element lying over the outer side of the hasp and confining the strap thereagainst, and a hinged flap lying at the back of: the hasp.

In testimony whereof we aflix our signatures in presence of two witnesses.
